Adjustable Head Ground Screw



1. Product Overview
Chudu Metal Hot-Dip Galvanized Solar PV Adjustable Head Ground Screw Pile is a foundation component designed for ground-mounted photovoltaic systems, particularly where convenient height adjustment and accurate connection with the upper solar mounting structure are required.
The upper section features an adjustable threaded head with a mounting plate and locking nut. After the ground screw is installed, the threaded connection allows the mounting plate height to be adjusted before final locking, helping accommodate installation tolerances and uneven ground conditions.
The mounting plate provides a bolted connection interface for solar mounting posts, columns, base brackets, beams, or other compatible structural components.
The lower section incorporates a helical screw structure for mechanical screw-in installation.
Manufactured from carbon steel with a hot-dip galvanized surface, the ground screw is suitable for outdoor and underground photovoltaic foundation applications.
Ground screw diameter, pile length, wall thickness, threaded adjustment structure, mounting plate dimensions, hole arrangement, helical dimensions, and other specifications can be customized according to customer drawings and project requirements.

4. Adjustable Head Structure
The main feature of this ground screw is the adjustable upper connection assembly.
The upper structure typically consists of:
- Mounting Plate
- Threaded Adjustment Rod
- Locking Nut
- Washer
- Ground Screw Connection Section
After the ground screw body has been installed into the ground, the threaded head can be adjusted to the required height.
The locking nut is then tightened to secure the final position before connecting the upper photovoltaic mounting structure.
This design provides additional installation flexibility compared with a conventional fixed-flange ground screw.
5. Adjustable Mounting Plate
The top plate provides the mechanical interface between the ground screw foundation and the upper solar mounting structure.
Different plate configurations can be manufactured according to customer requirements, including:
- Square Mounting Plate
- Rectangular Mounting Plate
- Customized Plate Shape
- Different Plate Thicknesses
- Different Bolt Hole Diameters
- Different Hole Quantities
- Customized Hole Spacing
- Customized Hole Layout
The mounting plate can be designed to match solar support posts, columns, base brackets, steel structures, or customized mounting components.
6. Height Adjustment
The threaded connection between the ground screw and mounting plate allows the upper connection height to be adjusted before final locking.
This feature can help with:
- Foundation Elevation Adjustment
- Installation Height Correction
- Mounting Structure Leveling
- Compensation for Ground Level Differences
- Alignment of Multiple Foundation Points
- Matching Upper Solar Support Structures
The actual adjustment range depends on the threaded rod length and connection design and can be customized according to project requirements.
7. Helical Ground Screw Structure
The lower part of the pile features a helical structure designed for mechanical screw-in installation.
During installation, rotational force drives the pile into the ground while the helical section engages with the surrounding soil.
The following parameters can be customized:
- Helical Blade Diameter
- Helical Pitch
- Number of Helical Turns
- Helical Section Length
- Blade Thickness
- Tip Structure
The final pile configuration should be determined according to project engineering requirements and actual site conditions.
8. Installation Process
1. Foundation Layout
Determine the ground screw positions according to the photovoltaic mounting system layout and engineering drawings.
2. Ground Screw Installation
Use suitable ground screw installation equipment to mechanically rotate the pile into the soil.
3. Installation Depth & Alignment
Control pile depth, verticality, and position according to project requirements.
4. Adjustable Head Installation
Install or adjust the threaded upper connection and mounting plate.
5. Height Adjustment
Rotate or reposition the threaded adjustment structure until the required mounting elevation is achieved.
6. Locking
Tighten the locking nut to secure the mounting plate at the required position.
7. Upper Structure Connection
Connect the solar mounting post, base bracket, column, or other structural component to the mounting plate using suitable bolts.
8. Solar Mounting Structure Assembly
Continue installing beams, purlins, braces, rails, and photovoltaic modules according to the system design.
